A team called G-Force consisting of five teenaged orphans Mark, Jason, Princess, Keyop and Tiny fight to defend Earth and its space colonies from the threat of the planet Spectra.

This series was derived from an adult anime "G Force" ( The Japanese Title Is Called "Scientific Ninja Team Gatchaman", Gactchaman is the 'G' in 'G-Force' ) violent scenes were cut and were replaced by a robot, 7-Zark-7, telling you a brief story of events.

It was reconstructed once again in the 80s as "G Force: Guardians Of Space" that is more accurate than the first adaptation. The Follow Up episodes of the original series was later adapted into another series. You can now own all the episodes of these series.
